G’day, Nikolai here from The Lawn Firm. One of the most powerful tools you have for growing a strong, green lawn is regular fertilising. But in Canberra’s climate, it’s not just about tossing fertiliser down and hoping for the best, you’ve got to get the timing, the type, and the method right. That’s where my experience across hundreds of ACT lawns comes in handy.

Why Fertilising Matters

Fertilising gives your lawn the nutrients it needs to grow thick, healthy, and resilient. Without it, grass struggles against weeds, pests, and weather extremes. The right fertiliser at the right time will:

Improve root development
Boost colour and density
Strengthen against drought and disease
Reduce the need for weed control

Understanding Canberra’s Lawn Growth Cycle

In Canberra, our lawns follow a seasonal growth pattern:

Spring: Time to wake up your lawn. Apply a balanced fertiliser to kickstart growth.
Summer: Apply slow-release fertiliser to support growth through heat stress.
Autumn: Use a fertiliser high in potassium to strengthen roots for winter.
Winter: Most lawns go dormant, so avoid fertilising unless addressing specific deficiencies.

Choosing the Right Fertiliser

There are three main nutrients to look for:

Nitrogen (N) – Promotes green, leafy growth
Phosphorus (P) – Encourages strong roots
Potassium (K) – Improves stress resistance

The Lawn Firm uses professional-grade blends chosen for Canberra’s soil conditions. We don’t just pick anything off the shelf; we know what each lawn needs based on experience and testing.

How to Apply Fertiliser Properly

Here’s how we apply fertiliser to get the best results:

Mow first, then apply fertiliser evenly across the lawn
Water in immediately unless using a slow-release product that requires dry application
Apply with care around garden beds and paths to avoid runoff

Getting the balance right is key. Over-fertilising can damage your lawn, while under-fertilising won’t give you the results you want.

Liquid vs Granular Fertiliser

Granular: Longer-lasting and great for routine feeding
Liquid: Fast-acting and good for quick results or addressing deficiencies

We often use a combination, depending on the season and the lawn’s condition. It’s this custom approach that sets our service apart.
